Book excerpt: First Amendment rights, particularly freedom of speech, play an integral part in all modern means of communication. Howard Stern has tested the limits and pushed the boundaries of freedom of speech to the delight of some and the disgust of others. Howard Stern: A Biography explores this long-debated topic and sheds light on how one media star has made a significant difference. Offering an engaging and insightful look at the life and career of radio's leading Shock Jock, the book explores Stern's youth, his first forays into radio, and his desire to move up in a competitive medium. Of course, it also covers his battles with the Federal Communications Commission, how he was finally able to sidestep the censors, and the significant changes the battle brought about in what is deemed acceptable on radio.
